We use many different techniques to graph lines, but one of the most efficient and straightforward, when given the equation of the line, is graphing lines using intercepts. If we are not given a table of values, the easiest two points to find are usually the x- and y-intercepts. Graphing lines using intercepts is not the only method, we can also graph using the slope and the y-intercept.

Whenever you're asked to graph a line,you have a choice of what methodyou want to use.

Some people like to graph linesby making an X-Y table.That's where you choose X values, substitutethem in one by one and find thecorresponding Y values.Use those as points and connect them.

Another method you guys might like touse is the slope intercept method.That's where you put your equationinto Y equals MX plus B form.Your first doc was at B that'sat the Y intercept.From there you count your slope and makeanother point and you connect them.Be sure to use a ruler.

The method I really want you guys to practicea little bit more and what you'regoing to see in your homework is thismethod 3. Finding and connectingthe X and Y intercepts.

The way to find X intercept is to substituteY equals 0. The way to findthe Y intercept is to substitute inX equals 0. It doesn't matterwhat form the equation is in whenyou start doing that process.

What you're going to end up with is twodifferent points on the two differentaxes and all you need to dois connect them using a ruler.

So if you guys get used to using all threeof these methods you'll get betterat being able to tell which methodis the best and the most efficientfor any given problem.
